2010 Impact Factors for fire related journals

The Journal Citation Reports has released the impact factors for 2010. The impact factor, one of the measures available to rank journals, is the frequency with which the "average article" in a journal has been cited in the previous two years. It is calculated dividing the number of citations to papers published in the previous two years by the total number of items published during the same period. In order and for fire related journals, these are:

#1 Progress in Energy and Combustion Science 10.36 (was 12.44 in 2009)
#2 Journal of Hazardous Materials 3.72 (was 4.14 in 2009)
#3 Combustion and Flame 2.747 (was 2.92  in 2009)
#4 International Journal of Wildland Fire 2.21 (was 1.90 in 2009)
#5 Building and Environment 2.13 (was 1.80 in 2009)
#6 Proceedings of the Combustion Institute 1.79 (was 3.51 in 2009)
#7 Engineering Structures 1.36 (was 1.26 in 2009)
#8 Experimental Thermal and Fluid Science 1.27 (was 1.23  in 2009)
#9 Combustion Science and Technology 1.11 (was 1.14 in 2009)
#10 Fire Safety Journal 1.02 (was 1.26 in 2009)
#11 Fire and Materials 0.96 (was 1.20 in 2009)
#12 Journal of Structural Engineering 0.83 (was 0.93 in 2009)
#13 Fire Technology 0.36 (was 0.37 in 2009)
#14 Journal of Fire Protection Engineering 0.15 (was 0.30 in 2009)

Clarification (derived from the wikipedia):
The 2010 impact factor of a given journal is equal to A/B. Where A is the number of times articles published in 2008 and 2009 were cited during 2010, and B is the total number of papers published by that journal in 2008 and 2009.
